I am planning on changing my washing machine from draining into my laundry sink into its own stand pipe. My laundry sink did not have a vent but wet venting up through the kitchen sink drain. I plan on adding 2 AAV's to take care of the venting for both the sink and washer drain. Does this make sense? Is the 4x4x3 wye correct on the kitchen sink drain? Are the 2 4x4x2 san-t's correct for each fixture? I assume the horizontal fitting to connect the AAV's would have to be a combo wye + 1/8 on its back facing the stack.

Many codes do not permit a pumped drain to have an AAV.
Check your local code.I stayed at a Holiday Inn Express last night.
Now I can Plumb!

Pumped? As in pumped out from the washer? If so then what?Comment

If an AAV is not allowed on the washer then a vent would have to be tied in above the kitchen sink. Check your local code!I stayed at a Holiday Inn Express last night.
